The Red Parasite is a special item in Manhwa Legends, the manhwa-inspired tower defense game on Roblox built by Blackcat Studios. It ties into the game’s unit-empowerment system, where certain characters can be given up to strengthen a target instead of being kept in your roster.
Quick answer: To empower the Red Parasite, sacrifice Ha Yori, Beylord, or Ha Yora.
How to empower the Red Parasite
The Red Parasite grows stronger through a sacrifice step. You feed it one of three eligible units, and that unit is consumed in the process. The units that qualify for the sacrifice are Ha Yori, Beylord, and Ha Yora. Any one of them can be used, so you do not need all three at once.

Because the sacrifice removes the chosen unit, plan around which one you are willing to lose. If a unit already holds a place in your active defense team, weigh that before handing it over to the Red Parasite.

Manhwa Legends runs on familiar tower defense systems. You summon units with gems, place them on the map, and clear waves of enemies across modes such as Story, Raids, and Portals. Units can be leveled, evolved, and rolled for traits that add stat buffs, and items like the Red Parasite feed into that growth loop.
The roster spans rarities from Rare up to Mythical, drawn from series including Solo Leveling, Tower of God, Omniscient Reader’s Viewpoint, The Boxer, and The Beginning After the End. Beylord appears among the Mythical-tier units, which makes it a notable choice to give up in the sacrifice.
Sacrifice options for the Red Parasite
| Eligible unit | Role in the process |
|---|---|
| Ha Yori | Consumed to empower the Red Parasite |
| Beylord | Consumed to empower the Red Parasite |
| Ha Yora | Consumed to empower the Red Parasite |
Note: You only need one of these units to complete the step. Pick the one you value least in your current lineup so you keep your strongest defenders on the board.
Manhwa Legends is live on Roblox, so the sacrifice step can be carried out in game rather than waited on. Keep an eye on your unit inventory before committing, since the trade is one-way once you feed a unit to the Red Parasite.
